A. Part IV (12VAC5-481-600 et seq.) of this chapter
establishes standards for protection against ionizing radiation resulting from
activities conducted pursuant to licenses or registrations issued by the
agency. These regulations are issued pursuant to the Act, as amended.

B. The requirements of Part IV (12VAC5-481-600 et seq.) of
this chapter are designed to control the receipt, possession, use, transfer,
and disposal of sources of radiation by any licensee or registrant so the total
dose to an individual, including doses resulting from all sources of radiation
other than background radiation, does not exceed the standards for protection
against radiation prescribed in Part IV (12VAC5-481-600 et seq.) of this
chapter. However, nothing in Part IV (12VAC5-481-600 et seq.) of this chapter
shall be construed as limiting actions that may be necessary to protect health
and safety in an emergency.
